(Bioreports)The governor of the state with the largest coronavirus outbreak said Tuesday that hospitalizations may be leveling off and social distancing “is working” — and people need to keep doing it.”Right now, we are projecting we are reaching a plateau in the number of hospitalizations,” New York Gov. Andrew Cuomo told reporters. “We have to stay disciplined. We have to be smart. We have to be safe. … We do that by staying at home.”Cuomo’s comments come as the US coronavirus death toll exceeds 12,000, and as health officials say parts of the country that leaned in heavily to social distancing measures may be seeing a slowdown in the growth of coronavirus cases. Cuomo offered mixed news: New York on Monday had its largest one-day increase in deaths for the state. But he said this was a lagging indicator, because often those who have died were hospitalized the longest.And the state’s three-day average for Covid-19 hospitalizations, and the daily intensive-care admissions, are down, he said.New York has reported more than 138,800 positive cases — a large chunk of the more than 386,000 coronavirus cases in the US, according to a tally by Johns Hopkins University.”I know (social distancing) feels like a lifetime,” Cuomo said, but “it is working.””That’s why you see those numbers coming down. If we had the same rate of interaction (from before stay-at-home orders) those rates would be going up.”In Boston, Mayor Marty Walsh warned cases in his city were just starting to spike — 33% of the city’s 2,035 cases were diagnosed in the last three days, he told Bioreports on Tuesday.”This is not the time to lax on any rules, as far as stay at home orders,” Walsh said. “We’re in this for the long haul.”The majority of people in the US are “doing the right thing” by staying home and following other mitigation measures to help fight the coronavirus pandemic, US Surgeon General Dr. Jerome Adams told ABC’s “Good Morning America.””I’m seeing mitigation work,” Adams said. “I know I’ve said it a couple times with Washington and with California. Their public health officials there should be applauded because they’ve given us the blueprint for how we deal with this and the rest of the country.”Recent developments• About 19.5% of the New York Police Department’s uniformed workforce were out sick as of Tuesday, a law enforcement source told Bioreports. At least 13 members have died of a suspected coronavirus case, the department said.• New Jersey, the state with the second most reported cases (more than 41,000), will close all state parks and forests and county parks to “further social distancing,” Gov. Phil Murphy said.• Major League Baseball says it is trying to work through plans to get back to playing, including possibly having games at a central location, once the coronavirus pandemic has improved.• Wisconsin is holding its primary election Tuesday despite the pandemic. The US Supreme Court allowed the vote, but a dissenting Justice Ruth Bader Ginsburg said the decision “boggles the mind.” • Adams, the surgeon general, told NBC’s “Today” show that Wisconsin voters should maintain distances of 6 feet from others and wear face coverings as they go to the polls.• White House trade adviser Peter Navarro warned the White House in January of a “full-blown pandemic, imperiling the lives of millions of Americans” from the coronavirus, The bioreports reports.• Michigan’s largest health care system, Beaumont Health, has about 1,500 of its more than 38,000 employees staying home with symptoms consistent with Covid-19, spokesman Mark Geary said.• Another large Michigan health care system, Henry Ford Health System, says 734 staff members — or 2.1% of its workforce — has tested positive for Covid-19 since it started tracking their status on March 12. Model predicts fewer people will die, compared to previous estimatesAn influential University of Washington model now predicts fewer people will die and fewer hospital beds will be needed, compared to its estimates from last week. But it assumes social distancing measures — like closing schools and business — will continue until August.Your coronavirus questions, answeredThe model predicts the virus may kill more than 81,000 people in the United States over the next four months, with just under 141,000 hospital beds being needed. That’s about 12,000 fewer deaths — and 121,000 fewer hospital beds — than the model estimated on Thursday, the Institute for Health Metrics and Evaluation at the University of Washington School of Medicine says. President Donald Trump warned Americans last week to prepare for a “painful” two weeks ahead as he extended nationwide distancing measures and acknowledged the severity of the virus. Both Dr. Anthony Fauci, the country’s leading health official and Dr. Deborah Birx, the White House coronavirus response coordinator, said Monday that with continued mitigation efforts, there is potential to lower a projected US death toll from 100,000.States helping each other with supplies To help states like hard-hit New York, California announced it was sending 500 ventilators to the US Strategic National Stockpile, which Trump previously said is nearly depleted. Track coronavirus cases in the US “We still have a long road ahead of us in the Golden State — and we’re aggressively preparing for a surge — but we can’t turn our back on Americans whose lives depend on having a ventilator now,” Newsom said in a statement.The 500 machines were scheduled to leave California on a military aircraft Monday to be shipped to FEMA, which will then redistribute to other states based on need, Brian Ferguson with the California Office of Emergency Services told Bioreports.Newsom isn’t alone — Oregon Gov. Kate Brown and Washington Gov. Jay Inslee have also offered ventilators to support other states.”These ventilators are going to New York and other states hardest hit by this virus,” Inslee said in a statement Sunday. The governor released 400 ventilators to the national stockpile. Virus hits African American communitiesAs states employ more tests to identify carriers of the virus, data has begun to show African Americans make up a large number of victims in the country. In Chicago, 72% of the people who have died from coronavirus are black, though they make up 30% of the population, officials said.In Louisiana, where nearly 33% of the population is African American, those residents account for 70% of the state’s coronavirus deaths. Dr. Celine Gounder, a Bioreports medical analyst and clinical assistant professor of infectious diseases, on Tuesday offered possible reasons for this, including:• African Americans may be disproportionately likely to work in essential jobs that can’t be done at home, such as grocery jobs.• African Americans are disproportionately likely to have underlying health conditions that would make someone more likely to have severe Covid-19 illnesses.Adams, the surgeon general, made similar arguments to “CBS This Morning” on Tuesday.”When you look at being black in America, No. 1, people unfortunately are more likely to be of low socioeconomic status, which makes it harder to social distance. No. 2, we know that blacks are more likely to have diabetes, heart disease, lung disease,” Adams told CBS.”I and many black Americans are at higher risk for Covid. It’s why we need everyone to do their part to slow the spread.” Bioreports’s Jacqueline Howard, Arman Azad, Ryan Young, Gisela Crespo, Jake Carpenter, Schimon Prokupecz, Wayne Sterling, Chandelis Duster and Steve Almasy contributed to this report.
